分割

This paper study classical segmentation methods and put forward a kind of synthetic segmentation method based on fractal parameter, the secondary statistics eigenvector of gray value.

本文在经典分割方法的基础上，提出了基于灰度的二次统计特征量－分形参数的图像分割综合法。

In image segmentation, whether or not find the eigenvector that can validly describe target area will directly influence the effect of segmentation.

在图像分割中，描述目标区域的有效特征向量直接影响分割的效果。

At first emendate the license plate, then utilize the quality of character, such as width of character and space between character, to segment the character. The method is simple and applied, and the result of segmentation is good.

先对车牌进行校正，再利用车牌字符的先验知识，根据字符的宽度和间距等进行字符的分割，实验表明这种方法简单、实用，获得较好的分割结果。

First, the non-brain structures removal was addressed to obtain the mask of encephalon, then the brain stem and cerebellum were separated respectively from the encephalon mask, and finally, two hemispheres were separated.

整个分割过程主要包括：首先从头部MRI图像中去除非脑组织，得到整个脑模板；然后分别从脑模板中分割提取脑干和小脑；最后分离左右两个脑半球。

We propose an approach to segment the epicardium and endocardium in cardiac image automatically.

通过对MR图像左心室分割中各种主流方法的分析，提出一种自动分割MR图像左心室内外轮廓的算法。

In order to segment the epicardium,the gradient vector components are reconfigured to generate the external force field.

这种外力场能够克服原始梯度矢量流的不足，使得室壁外膜边缘很弱时也能得到保持，以左室壁内膜分割结果作为初始化能够自动地分割出左室壁外膜。

With these strategies , taking the final contour for endocardium as initialization , the Snake contour is reactivated to locate the epicardium automatically and accurately .

基于所有这些策略并采用内膜的分割结果初始化，可以自动，准确地分割外膜。

As the distance between epiphysis and metaphysis is relatively close, it can prevent the contour from closing toward the edge of epiphyseal structure which has been divided in the first step, to set a perpendicular to the x-axis of region of interest in the segmentation process.

由于骨骺和干骺相离较近，在分割过程中设定一个垂直于兴趣区域x轴的直线，防止轮廓向着第一步中已经分割好的干骺骨结构边缘靠近。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
